sometimes we have several assertions with the same condition in the same test
at different stages, and when these fail (the ones that print the condition
text) you don't know which one it was. other assertions didn't print the
condition text (variable names), just the expected and unexpected values.
So now, all assertions print context line, and conditin text.
besides, one of the major differences between 'assert' and 'assert_equal',
is that the later is able to print the value that doesn't match the expected.
if there is a rare non-reproducible failure, it is helpful to know what was
the value the test encountered and how far it was from the threshold.
So now, adding assert_lessthan and assert_range that can be used in some places.
were we used just 'assert { a > b }' so far.
* allowing --single to be repeated
* adding --only so that only a specific test inside a unit can be run
* adding --skiptill useful to resume a test that crashed passed the problematic unit.
useful together with --clients 1
* adding --skipfile to use a file containing list of tests names to skip
* printing the names of the tests that are skiped by skipfile or denytags
* adding --config to add config file options from command line
This replaces individual ziplist vs. linkedlist representations
for Redis list operations.
Big thanks for all the reviews and feedback from everybody in

It is now possible to kill and restart sentinel or redis instances for
more real-world testing.
The 01 unit tests the capability of Sentinel to update the configuration
of Sentinels rejoining the cluster, however the test is pretty trivial
and more tests should be added.
Now it uses the new wait_for_condition testing primitive.
Also wait_for_condition implementation was fixed in this commit to properly
escape the expr command and its argument.
A new primitive wait_for_condition was introduced in the scripting
engine that makes waiting for events simpler, so that it is simpler to
write tests that are more resistant to timing issues.
